VALVE MECHANISM FOR GAS-RETORTS.

iaaaoae.

T 0 all whom it may concern:

Be it known that I, HENRY A. CARPENTER,

a citizen of the United States,residing at Mechanism for Gas-Retorts, of which the following is a specification;

This invention relates to that type. of coal gas generating apparatus wherein communication between a retort and stand-.plpe or other gas oiftake is controlled, by a valve,-

and has particular referenceto jimproved means for insuring movement'of the valve to closed position, before opening theretort door, thereby forestalling inadvertent opening of the door when the valve is open,and preventing either escape of gas from the oiftake to the atmosphere, or inrush of atmospheric air into the gas ofitake.

In the accompanying drawing, which illustrates an application of my invention,

Figure 1 is a part plan and a part sectional view of a retort mouth-piece shown in connection with a stand-p1pe and with valve mechanism and retort closure means; Fig. 2 is a front elevational view; Fig. 3 is an enlarged side elevational view; and Fig. 4 is a detail View partly intelevation and partly in section, the section being taken on line lVIV of Fig. 3.

As illustrated and as preferred, the

mouthpiece 1 is designed to be connected with a stand-pipe 2. In practice, the standpipe 2 is usually interposed between two rows of retorts or between-the mouthpieces.

1 thereof, said stand-pipe 2 being provided with openings 3 in opposite faces thereof,

respectively designed to communicate with an outlet opening'of a nozzle or an extension-4: formed integral with the mouthpieces. This extension 4 is designedto abut againstthe stand-pipe and as shown,is of substantially the same height as the mouthpiece but of comparatively short length. The walls of the extension form a chamber of sufficient dimensions to receive a valve and a portion of a. valve actuating-mechanism, and the chamber so formed is conveniently accessible for cleaning and other purposes through the front opening of the mouth-piece. v 1

As illustrated, the nozzles or extensions 4 are each provided with a seat 5 and with a Specification of Letters Patent.

flange 6 adapted to be entered in a face of 'the stand-pipe with the opening 3 ofthe stand-pipe registering with the outlet pasin closed position to rest upon the seat 5 of. vthe extension 4. Said valve 7 is secured on an end of a bent arm 8 by a universal joint c0nnect1on9. The arm 8 is secured to or made integral with a horizontally extending shaft 1Q projecting outwardly from the mouth-piece and having its bearing ina casmg 11. The outer end of the shaft 10 is preferably shaped as shown at'12 to permit a' tool (not shown) to be placed thereon by which the shaft 10 together with its arm 8 are moved. 7

In constructions of this character employing afvalve for controlling communication between the retort or the retort mouthpiece and theYstand-pipe, it is essential that the space or passage-way through which the gas passes from the retorts to the standpipe should be easily accessible, preferably through the outer opening or end of the mouth-piece, for the purpose of cleaning the connection space or passage-way when the valve is closed or seated; and the construction illustrated is particularly adapted for this purpose. The general arrangement above described is also particularly effective in maintaining the valve seat substantially free from deposit. The valve 7, being practically swiveled and movable in an arc toward and away from the seat 5, has a tendency, during its movement toward the seat, to shift its position on the ball 9, the

result being that this shift must be correct ed by the valve seatin order to permit the valve to properly seat, and this correcting action has the eifect of 'providing a relative .movement between thevalve and seat such as would remove the deposits on the seat, 100

passage-way, and is conseqluently notliable 105 to collect deposit, especial y asthe curved face of the valve extends toward such path.
